不应该调用MPMoviePlayerPlaybackDidFinishNotification

Question

根据Apple的MPMoviePlayerController doc:

MPMoviePlayerPlaybackDidFinishNotification - 如果电影播放器​​以全屏模式显示并且用户点击完成按钮,则不会发送此通知.

在我看来,这是错误的.使用下面的代码,当我点击完成按钮时,会调用pl​​ayerPlaybackDidFinish.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerPlaybackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.player];

- (void) playerPlaybackDidFinish:(NSNotification*)notification
{
    NSLog(@"WHY?");
    self.player.fullscreen = NO;
}

我需要区分用户点击完成按钮和电影完成整个播放.当电影结束时,playerPlaybackDidFinish会被调用,但就像我说的那样,当你点击Done时它也会被调用.

以下是检查MPMoviePlayerPlaybackDidFinishReasonUserInfoKey的方法,这是MPMoviePlayerPlaybackDidFinishNotification通知的一部分

- (void) playbackDidFinish:(NSNotification*)notification {
    int reason = [[[notification userInfo] valueForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] intValue];
    if (reason == MPMovieFinishReasonPlaybackEnded) {
        //movie finished playin
    }else if (reason == MPMovieFinishReasonUserExited) {
        //user hit the done button
    }else if (reason == MPMovieFinishReasonPlaybackError) {
        //error
    }
}

当您收到通知时，您可以检查播放器的 endPlaybackTime。如果是-1，那么电影就自然结束了。

对于流媒体内容，您可以检查 MPMoviePlayerPlaybackDidFinishNotification 上 userInfo 内的 MPMoviePlayerPlaybackDidFinishReasonUserInfoKey。

如果它等于 MPMovieFinishReasonUserExited 则表示用户停止播放内容。
